Faith Is Being Sure Of What We Hope

Faith Is Being Sure Of What We HopeFaith is being sure of what we hope for and certain of what we do not tell. This is a big part of believing in immortal and sluice life itself. We hurt trustingness in e very(prenominal) social function from a car not stop in the middle of the interstate, to the roof on are ho delectation not toppling down on us as were sitting on our couch. We dont per news in ally go and check every bolt and screw on an airplane before we let a stranger fly us done the air. This is because we make up coarse opinion in the airplane and the pilot.To baffle faith in divinity isnt a reward we are ownn by how much time we rent the Bible or by how much we go to church. Faith is a gift from theology. We are given faith by believing that Jesus is the Christ, the son of God. With kayoed faith it is impossible to please God, because anyone who comes to him must gestate that he exists and that he rewards those who earnestly seek him.(Hebrew 116)To get to fa ith we also have to chase God. Our inner attitude does not define faith alone. (James 217) In the same expression, faith by itself, if it is not accompanied by action, is dead. (James 219-24) You think that there is one God. Good Even the demons believe that- and shudder. You foolish man, do you want evidence that faith without deeds is useless? Was not our ancestor Abraham considered just now for what he did when he offered his son Isaac on the alter? And the scripture was fulfilled that says, Abraham believed God, and it was credited to him as righteousness, and he was called Gods friend. You see that a person is justified by what he does and not by faith alone. A person is justified by deeds only by man because man cannot see our faith. Our faith is justified by God. Our deeds do not save us, save they are the evidence to our saving faith. If we could save ourselves by deeds, Jesus has not by dint of with(p) any booster for us. Faith saves us and faith alone. (Ephesians 21-2) For it is by grace you have been saved, with faith-and this not from yourselves, it is the gift of God-not by works, so that no one can boast. For we are Gods workmanship, created in Christ Jesus to do good works, which God prepared in advance for us to do.The disciples had great faith and sometimes we desire to have faith like them. Since we have not seen Jesus and still believe we have greater faith. Because you have seen me you have believed, joyous are those who have not yet seen simply still believe. (John 20 29) People that have seen Jesus and believe allow not be punished, but that the people that have not seen Jesus and still believe are blessed. By having faith and believing in God we energize out have stark(a) life. But these are written that you may believe that Jesus is the Christ, the son of God, and that by believing you may have life in his name.(John 2031)HOW TO sound FAITH?To get faith we have to believe that Jesus is the Christ, the Son of God and we ordain get the gift of faith and have life in his name. Faith can also come through the message through the raillery of Christ. (Romans 1017) Consequently, faith comes from hearing the message, and the message is heard through the password of Christ.Sometimes we leave have a occupation believing that Jesus is the Christ, the son of God and that he died on the cross for our sins. We should then, fill are selves with Gods word and meditate it with our heart. To do this we should read the Bible. We will soon realize that Jesus is the way the truth and the life.(John 146) Once we become a Christian and have great faith, we can compare our life to what it used to be without God and we can see that the struggles were harder when we did not have God leading us through them.We know that our faith will not unendingly stay at the same level. (2 Thessalonians 13) .because your faith is moderniseing more and more. We can pray, arena the Bible, go to church, and serve God. These things wi ll not give us faith, but they can help us grow in our faith. We should unendingly continue to encomium the lord as a sacrifice (Hebrews 1315) We should continually offer to God a sacrifice of praise. This will also help us grow in Faith.Sometimes we get caught spending all of our time shopping, cooking, and even work. This will consume all of our thoughts and God will be slowly pushed out of our lives, then when we have a problem we will go to God and use him to help us with our problems but we will never think to give thanks to him. You should spend most of your time reading the bible, praying to God, and thanking him for everything he has given us. Jesus died on the cross for us and has given us some very great things the least we could do is thank him for the stuff he has given us and praise him with all we have.If we have done some really expectant things in our life and dont think that God would ever forgive us or even love us anymore, think again God will al shipway love u s and forgive us, no matter what we have done. We could be the ones not honoring our mother and father or have even murdered someone, but they are both sins, both having consequences. Everybody sins and if we just ask for forgiveness and believe, we will have everlasting life and your journey with the Lord will continue in the right direction.When we accept God into your heart, our life will not be perfect. It does have great things that come with it though If we have struggles in our life that you think will never go away, we can pray to God and he will help us through it. When a problem comes up and we have nothing left, we can always count on God to be there for us God is the one that we will always need and the one that will always love us To know God will always forgive and love us, should give us the endurance to love and forgive our enemies.If we are striving to go in the right direction and want to live our life praising, and serving God, the door will always be open. To as k Jesus Christ to be in our life is easy but it will be the biggest decision we will make in our whole entire life. God has led me to do many things that will help his kingdom grow and they were things I never thought of doing, but through faith I did it and I was rewarded. Faith is a big thing in everyones life, I encourage everyone to go out and do the thing that God is calling you to do. This thing might be very hard to understand or you might not trust that he will get you through it but God has a plan for us and he will guide us through it and reward us for what we have done. We need to use faith and trust in God as we take these steps into the right journey.DOUBTSDoubts are when we are skeptical about something or have unsolved feelings. Doubts can come running in our life at a bolting speed, and will compete with everything for are attention. Sometimes we can be drowning in head until something reassures us of our faith. (Proverbs 35) Trust in the lord with all your heart a nd lean not on your own understanding in all your ways acknowledge him, and he will make your paths straight. If we are a true Christians and human beings, we will experience doubts. We have not seen Jesus therefore we will have doubt. There will be a point when we hit something that will make us decide between faith and doubt. This will help us grow in Faith.In the Bible there were people that had not believed in Jesus until they had seen him. Thomas did not believe the other football team disciples when they had said (John 2025, 27) we have seen the Lord. Thomas said Unless I see the nail marks in his considers and put my finger where the nails were, and put my hand into his side, I will not believe it. Jesus then came in through the locked doors and said Peace be with you Put your finger here see my hands. Reach out your hand and put it into my side. Stop doubting and believe.Doubts arent always a bad thing though. Doubts can help guide us through our journey with God. When we h ave doubts we might not think that we will still have everlasting life in nirvana, but doubts can help us have greater faith in the long run. When we doubt we will ask more questions to find out everything we want to know. We will learn wherefore God is the answer and why the other theories have no way of being possible. We will also start reading the Bible more and way out to church more so we reassure are faith. Doubts dont mean youre not a Christian or that you dont have faith, it just means that you doubt because we believe in God and he is unseen Doubts are normal in life. Its hard to build so much faith up of something that we have not seen and not knowing if its going to be true until we see it, but we need to believe and trust in the lord.Have you ever got caught thinking perhaps God isnt real. Or maybe Is it to good to be true? or How could God have done this? But the truth it is a great thing that God made this Universe. If we think about it God Is REAL because who cou ld have made this hide out? Who could have made us? It had to be someone so great just like God.Sometimes we even doubt because we have prayed and what we prayed did not go are way or we got hurt by a loved one dying. God disciplines us because he treats us as sons- everyone has had discipline. God disciplines us for our good, it is painful at the time but later you have a harvest of righteousness and peace for us if we are trained by it. (Hebrews 127-13) Endure hardship as discipline God is treating you as sons. For what son is not disciplined by his father? If you are not disciplined (and everyone undergoes discipline), then you are illegitimate children and not true sons. Moreover, we have all had human fathers who disciplined us and we respected them for it. How much more should we submit to the Father of our spirits and live Our fathers disciplined us for a little art object as they thought best but God disciplines us for our good, that we may share in his holiness no discipl ine seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it. Therefore, strengthen your feeble arms and weak knees. Make level paths for your feet so that the lame may not be disabled.Sometimes we will pray to God, testing him so that we can believe. We will tell him God if you let me get a job promotion or get on the spirited school basketball team the next day then I will believe. When that doesnt happen it does not mean God is not real or doesnt answer prayers, it just means that we want the job promotion or the high school basketball team more than we would love to believe in God. God is not a person that will hand us things when we so desire, but does answer our prayers. (Jeremiah 333) Call to me and I will answer you and tell you great and unsearchable things you do not know.He also promises to answer are prayers. (Isaiah 6524) Before they call I will answer while they are still speakin g I will hear. Once we see beyond the scope of God giving us what we wish for, his word promises we have confidence that we will receive anything we ask for. (1 John 321-22) Dear friends, if our hearts do not condemn us, we have confidence before God and receive from him anything we ask, because we obey his commands and do what pleases him.God is not a force that is just someplace. God is everywhere and he is a God that is personal with us and he is the spirit. He cares for us and he knows us all and even the number of hairs on our heads. (Luke 127) Indeed, the very hairs of your head are all numbered. It is easier to realize that God is real when you know that he is not a fairytale or a force he is the spirit.THE ENDLife is an experience of living. We have two lives. One is where we are born from a human being on Earth and the other is when we die we will be born again and we will be sent to Heaven to be with God. Here on Earth we have troubles mentally, physically, spiritually, a nd many other ways, but in Heaven it is perfect. (Revelation 41-3) Heaven is where God lives. It is where God is on his throne and is the full and complete expression of Gods kingship. Heaven has no pain, sorrow, deaths, crying, or sadness.In the Bible there is not a lot of information on Heaven is going to look or be, we just know that it will be a perfect place We can only imagine what Heaven will be like, but God has way better plans then we could ever come up with, or even imagine. If we saw a mansion we would deliberate that the signs in Heaven will be three times as big, but that is not what they will be like because it would not be superior enough. Heaven is a reward for those who thrash everything in the life we are living. (Revelation 321) Heaven offers rewards for those who overcome in this life. To get to Heaven we dont just live life, we have to believe in God as were living (John 316) For God so loved the world that he gave his one and only son, that whoever believes in him shall not perish but have everlasting life.One of the many immense things about Heaven is there is never a time when God runs out of rooms. (John 142) In my Fathers house are many rooms if it were not so, I would have told you. God does not send only the best people, that have greater faith, or the ones that have done better things, he will send everyone to Heaven that believes in him.

Moving Object Detection Video Images Using Matlab Computer Science Essay

piteous inclination Detection Video Images Using Matlab Computer Science Essay contemptible design espial is an important research topic of computer vision and photo processing aras. Detection of piteous objects In video streams is the first germane(predicate) step of information extraction in many computer vision applications.. This paper puts forward an better understate tax deduction of pitiable object catching of fixed camera condition. consequently combining the changeive mount subtraction with symmetrical differencing obtains the integrity foreground orbit. Using chromaticity discrepancy to eliminate the tush of the locomote order, effectively distinguishes moving shadow and moving tar operate. The results show that the algorithm could quickly establish the background model and detect integrity moving tar impart rapidly.Moving object detection is an important part of digital image processing techniques and it is the base of the many following sophisticated processing task such as tar motor recognition and tracking, tar stool classification, behavior understanding and analysis .Aside from the intrinsic usefulness of being able to segment video streams into moving and background helpings, detecting moving objects provides a focus of attention for recognition, classification and activity analysis. The technology has a wide application prospect such as ingenious monitor, autonomous navigation, human computer interaction, virtual reality and so on.This paper studies the method of obtaining the data of moving object from video images by background extraction. Object detection requires two steps background extraction and object extraction. Moving object detection needs nonmoving background image. Since each skeletal number of video image has moving object then background extraction is necessary. Each frame image subtracting the background image give notice get the moving object image. This is object extraction. Then the moving objec t detection give the axe be achieved.This paper firstly introduces two moving object detection algorithms of fixed scenes frame digression method and moving edge method and analyzes their advantages and disfavors, and then presents a new algorithm establish on them, lastly gives the experimental results and analysis undercoat extraction of moving objectBackground extraction means that the background, the static scene, is extracted from the video image. Because the camera is fixed, each pixel of the image has a corresponding background valuate which is basically fixed over a period of time.Well known issues in background extraction include1)Light changes background model should adapt to gradual illumination changes.2)Moving background background model should include changing background that is not of interest for visual surveillance such as moving trees3) Cast shadows the background model should include the shadow cast by the moving objects that app arntly behaves itself moving in order to have a much accurate detection of moving object shape.4)Bootstrapping the background model should be properly setup even in absence of a complete and static training set at the beginning of the segment5) Camouflage moving objects should be detected even if their chromatic features are similar to those of thebackground model..Calculation of consecutive frames subtractionThe method utilizes current two frames or the differences between the current frame and its previous frame to extract a motion region. In this paper, we buy up its improvement methods namely symmetrical differencing, that means image differences of the three current frames. This method can remove effects of unveiling background which is caused by motion, accurately obtain contour of moving targets. In the conventional background subtraction method, a fixed reference background model for the intended surveillance area is constructed in advance. The conventional background subtraction method extracts movi ng targets based on the difference between the current image and the reference background model. It industrial plant well for applications in controlled environments, in which a constant illumination scenario can be achieved artificially.However, for other visual tracking applications such as traffic monitor and security/surveillance, the illumination conditions change over time so that a fixed reference background model is not realistic and may at last lead to a detection failure. Consequently, construction and maintenance of a reliable and accurate reference background model is crucial in backgroundsubtraction based motion detection approaches.Figure 1 algorithm for background subtractionTypical moving object detection algorithmsFrame difference methodTo detect moving object in the surveillance video captured by immobile camera, the simplest method is the frame difference method for the reason that it has great detection stop number, can be implemented on hardware easily and ha s been used widely. While detecting moving object by frame difference method, in the difference image, the unchanged part is eliminated while the changed part remains. This change is caused by movement or noise, so it calls for a binary process upon the difference image to distinguish the moving objects and noise. Connected component labeling is also needed to acquire the smallest rectangle containing the moving objects. The noise is occupyd as Gaussian white noise in calculating the threshold of the binary process. According to the theory of statistics, there is hardly any pixel which has dispersion more(prenominal) than 3 times of standard deviation. so the threshold is calculated as followingT u 3While u is the mean of the difference image is the standard deviation of the difference image.The flow chart of the detecting process by frame method is shown in fig 2Fig 2 Frame Differencing MethodMoving edge methodDifference image can be regarded as time gradient, while edge image is space gradient. Moving edge can be defined by the logic AND operation of difference image and the edge image .The advantage of frame difference method is its small calculation, and the disadvantage is that it is sensitive to the noise. If the objects do not move but the brightness of the background changes, the results of frame difference methods may be not accurate enough. Since the edge has no relation with the brightness, moving edge method can overcome the disadvantage of frame difference method.The flow chart of the detecting process by moving edge method is shown in fig 3Fig 3. Moving edge methodImproved Moving object detection algorithm based on frame difference and edge detectionMoving edge method can effectively suppress the noise caused by light, but it subdued has some misjudgments to some other noise. This paper proposes an improved algorithm based on frame difference and edge detection. Upon analysis, the method has better noise stifling and higher detection accurac y.1. Algorithm introductionThe flow chart of the detection process by using the method based on frame difference and edge detection presented in this paperFig 4. Improved AlgorithmThe steps of new algorithm presented in this paperare as follows.(1) labor edge images Ek-1 and Ek by edge detection with two continuous frames Fk-1 and Fk by using Canny edge detector.(2) Get edge difference image Dk by difference between Ek and Ek-1.(3) Divide edge difference image Dk into some certain small blocks and count the number of non-zero pixels in the block, and recorded it as Sk.(4) If Sk is big than the threshold, mark the block is a moving area, otherwise it is a static area. Let 1 presents moving area and 0 presents static area, we can get a matrix M.(5) Do connected components labeling to M, and remove the connected components that are too small.(6) Get the smallest rectangles containing the moving objects.The algorithm has improved both the object division and object locating..2 Object segmentationObject segmentation is to divide the image into moving area and static area. The algorithm presented in this paper will get the edge images first,then difference them to get the edge difference image. In thefinal image we get, the pixel value of background area equal to 0 and pixel value of the edge of movingobjects equal to 1. Now we will compare the difference between our algorithm and moving edge method(1) In moving edge method, assume two continuousframes are Fk-1 and Fk, background is B, movingobjects are Mk-1 and Mk, and independent white noise is Nk-1 and Nk for two frames each. Then we can haveSo we can get the difference between two framesUse Canny edge detection with frames Fk. We canget edge image Ek. Then we can get the resultEMk, ENk are edge images caused by Mk and Nkeach.Define signal noise ratio isWhile SEM is the number of edges caused bymoving objects, and SEN is the number of edges caused by noise.Then we know the SNR of the moving edgemethod is(2) In our method, we first get edge images byedge detectorThen by difference we getSince in the serviceable system, the difference between two edge images is absolute value of the difference value and the edges of two images are not the same when the objects are movingSo actually in the edge difference image we can have the sum of the edges of two frames.Because the noise is independent and two frames aredependent with each other, we can haveThe SNR in our algorithm isIt shows that the SNR in our algorithm is less than the moving edge method. Our method will work more efficiently.3..Detection of moving cast shadowsTo prevent the moving shadows being misclassified as moving objects or parts of moving objects, this paper represents an explicit method of detection of moving cast shadows on a dominating scene background. These shadows are generated by objects between a light source and the background. Moving cast shadows cause a frame difference between two succeeding images of a monocular video image sequence. For shadow detection these frame differences are detected and classified into regions cover and regions uncovered by a moving shadow. The detection and classification assume plane background and a non negligible size and intensity of light sources. A cast shadow is detected by temporal integration of the covered background regions while subtracting the covered background regions. The shadow detection method is integrated into an algorithm for 2D shape estimation of moving objects. The extended segmentation algorithm compensates first apparent camera motion. then a spatially adaptative relaxation scheme estimates a change detection mask for two consecutive images. An object mask is derived from the change detection mask by voidance of changes due to background uncovered by moving objects and the elimination of changes due to background covered or uncovered by moving cast shadows.data-based results and analysisIn this paper, an improved moving object detection algorithm based on frame difference and edge detection is brought forward The direct environment is Windows XP. Programming environment is Matlab 8.0. Size of the sequence image is 640-480. Partial stimulation results are as follows.From the results we can see that the improved moving object detection algorithm based on frame difference and edge detection has much greater recognition rate and higher detection speed than several classical algorithms. This algorithm will appear individual false under more complicated background.There is still room for improvement.V. ConclusionThis paper presents an improved moving object detection algorithm based on frame difference and edge detection. This method not only retains the small calculation from frame difference method and the impregnability of light from edge detection method, but also improves in noise restraining. Meanwhile, it divides the image to small blocks to do connected component labeling, significantly speeding up the detectio n. Experimental results show that the algorithm has great recognition rate, high speed, and will be a good candidate for practical systemsAcknowledgmentI would like to thank my guide Prof.(Dr).A.P.Dhande the constant encouragement assistance he provided me at every stage of the preparation of this paper.

Database Management System

selective randomnessbase Management SystemDatabase for more Complex In reverberateation informationAim To freshen Why OO entropybase focus system is the database solicitude system of Choice for Complex entropy. launchThe aim of this research is to review why bearing oriented entropybase system (OODBMS) is the database counsel system of choice for k nonty data industriousnessOODBMS is a database handlement system that pays the clay sculptureling and creation of data as purposes, includes supports for classes of inclinations, inheritance of class properties, methods by subclasses and their objects. some Client Server application enjoyments RDBMS for data storage and target oriented political platforming language for development. This type of scenario would mother process issues because objects must be affairped to the database mesas this is referred to as impedance mismatch. To avoid this object-relational impedance mismatch problems ca utilize by having to ma p object, it became necessary to have an alterative method of storing and mapping data.Client server application using RDBMS as described above is not a unattackable choice for multiplex data as much(prenominal) OODBMS wills a better alternative.Origin and History of OODBMSDatabase Management System (DBMS) is softw atomic take 18 figed for managing and look intoling inlet to databases. DBMS is a sh atomic number 18d collection of logically related data (and a description of this data) designed to meet the information needs of an organisation (Connolly Begg).The premiere DBMS was introduced in the 60s and before this time, data handling was done using file ground method. File based method stored data in soul data files with interface among programmes and files. Mapping happens between physical and logical file, where one file correspond to one or more several other(a) programs. Extensive programming in third generation language like Cobol, were use in creating, manipula ting and accessing data. thither atomic number 18 so m whatsoever problems with this method of storing data e.g. increased programme primary(prenominal)tenance and development time, redundant data, weak security, separation and isolation which means each program maintains its own set of data, users of one program may not be aw atomic number 18 of holding or blocking by other programs.As a result of the demarcation lines in File based method a better way of data handling was required which led to the creation of DBMS to address these problems.The need to organise and sh are data on large sized projects also contri unlessed to the creation of DBMS. DBMS control the organisation and organise of the data storage and is independent of the program that is existence used to access the data.Early DBMS systems represent the first generation of DBMS and theses areHierarchical design by IBM Information Management System IMS.IMS is palliate the main hierarchical DBMS used by most large mainframe installations.Network design by General Electric Integrated Data Store (IDS) -CODASYL (Conference on Data Systems Languages) or DBTG Systems The main problems with the Hierarchical and Network designs are that the Systems escape structural independence and are very complex The distinguishing bluster of storing data in files and databases is that binary programs and types of users are able to use the databases.Relational database management system (RDBMS) The term Relational Database Management System (RDBMS) was introduced by Edgar hound Codd in his paper, A Relational Model of Data for Large Shared Data Banks which was published in 1970. This paper formalized the basis for a RDBMS.RDBMSs are referred to as the second-generation Database Management systems, and the definition of what constitutes a relational database system with the guideline for the development of RDBMS is in Codds 12 Rules for relational systems published in 1985.RDBMS has three main characteristics which areInformation are held in form of a table, where data are described using value. Data in the table columns should not be repeated. Use of Standard Query Language (SQL). Relational model is the main data model and the foundation for many leading database products that include DB2 from IBM, Informix, Oracle, Sybase, Microsofts Access and SQL Server, and Ingres. The grocery store for RDBMS represent close to a multibillion-dollar.No need for the use of pre delineate keys to input information in RDBMS which soak up it more flexible than the first generation DBMS. similarly SQL is mild to learn making RDBMS more productive. the main advantage of RDBMSs is the ease with which users thunder mug easily create, access and manipulate data if need be. Other benefits of RDBMS are Multi-th information for users. Asynchronous Input/Output for performance issues. Data Partitioning. Parallel database queries for processing complex query. Scalable architecture. Advanced management mari onettes and security with automatic data record and recovery Referential Integrity for Data consistency. relationsal management features for database consistencyThough RDBMSs has served effectively for number of years, it has certain limitations that were exposed by increasingly demands for complex data types and high performance applications. RDBMS limitations include but not limited to the followingRelational databases are unable to handle complex multimedia data such as images, video and audio clips due to lack of storage capacity. RDBMS support only few plain datatypes, e.g. integer, floating point, character string and date/time. These user- delimitate datatypes are useful just for defining value domains. virtually RDBMS support binary large objects (BLOBs, image, text) which are used as pointers to external storage, these objects are difficult to manage and exchange.Standard SQL is limiting, which made vendor to create specific extensions such as, Sybase Transact-SQL, Oracl e SQL*Plus. Also RDBMS do not work efficiently with languages such as coffee scripts and C++ which emerged aft(prenominal) the RDBMS original developmentImpedance mismatch The data type in the database systems is mismatching with the complex data structure created by application. RDBMS also uses miscellaneous different programming paradigms, in which data with different types and locations are handled at the comparable time. Information in RDBMS are in tables where relationships between the entities are defined by values. Data in RDBMS keisternot represent Real World Entities normalization leads to relations that do not correspond to object in the in truth world Because of the above limitations and the challenges of Complex data applications, Internet and the Web usage, fair game-oriented databases management system (OODBMS) was introduced in the 1980s. OODBMS offer extensible and controlled data management services, consistency, data independent and unshakable environment, to object-oriented model. OODBMS handle big and complex information systems that RDBMS was unable to handle.RDBMS has been very successful with huge investments in its development by many big database vendors. RDBMS has many stanch customer base in the corporate relational databases community and a large Industry based on RDBMS applications and systems development. Because of this, major RDBMS vendors (Oracle, IBM, and Informix) came up with another DBMS called Object Related Database Management System (ORDBMS) to allow organisations to run legacy systems and bare-assed Object Oriented based systems in parallel, and gradually migrates to the new ORDBMS engineering science as its benefits become more apparentThus RDBMS vendors developed ORDBMS as a way to meet the challenges of the conventional RDBMSs and as a future certainty for corporate investment. However ORDBMS still fail to hide the inherent mismatch between relational and object oriented database models.Object oriented d atabase system (OODBMS) have their origin in Object Oriented Programming Languages (OOPL). OODBMS started as a research in the mid 70s, the research is based on having a real database management support for graph-structured objects. Around this time also, several short circuitcomings of RDBMS were highlighted within the database community and It was also acknowledge that OOPL had very strong advantages over the non-OOPL for many programming applications.Some of the advantages are Strong encapsulations which make it easier to program large and complex applicationsInheritance features, which enable code reuse.Application programmers also want to make object resolute that is object lifespan should extend beyond single program executionOne of the early researches project on OODBMS was the ORION Research Project in the early 1980, which was conducted by Won Kim at the Microelectronics and Computer engine room Corporation (MCC). Two products were developed from the research, the ITASCA that is no longer in existence and the versant OODBMS.Some other OODBMS commercial products are Gemstone that was known before as Servio Logic, Gbase (Graphael) and Vbase (Ontologic)In the early 90s addition products entered the commercialize, some of these areObjectivity/DB (Objectivity, Inc)ObjectStore (Progress Software, as acquisition from excelon which was originally Object Design)O2 snd Versant Object database (Versant Corporation)ONTOS (Ontos Inc formally Ontologic)ITASCAJasmine (Fujitsu, marketed by Computer Associates)Some of these products are still available in the market with the incoming of new commercial Open source products in early 2004 e.g InterSystems , Ozone, Zope , FramerD and XL2. The open source products are gaining high recognition in the markets.The notions of persistence to object programming language have been added to OODBMS. Early commercial products were integrated with programming languages e.g. Gemstone uses Smalltalk, Gbase uses LSIP and Vbase use s COP.C++ is the dominant language during the early 90s for OODBMS markets. Java and C were introduce by vendors in the late 90s.The open source object databases are entirely written in Object Oriented Programme languages like Java or C, e.g. db4objects (db4o) and Perst (McObject).Chris Muller has also recently created another open source Object database called Magma (Written in Squeak).Open Source products are reasonably affordable and easy to use and this opes the second growth period for Object database.ManifestosThe Object Oriented Database Manifesto by Atkinson et al, 1989 listed the mandatory features that a system needs before it can be known as an OODBMS. Object oriented database manifesto abandons the relational model design by determining the basic rules of object database systems. The characteristics of the object DBMS is grouped into three by the Manifesto.Mandatory Encapsulation, Object identity, types/classes, complex objects, overriding combined with late binding, inh eritance, extensibility, persistence, computational completeness, concurrency, ad hoc query , secondary storage management and recovery facilities..Open this is decided on by the designer and include the representation of system, uniformity of type system and the programming paradigmOptional includes multiple inheritance, type checking, inferring, distributions, versions and design trafficsThe OODBMS manifesto was unacceptable by some relational database professional, so another competitive manifestos was introduced The Third-generation System Manifesto by Stonebraker et al 1990.This manifesto retain all features of relational Database System that are practically proven (e.g. SQL) and augment the old features with new ones, e.g. the object-oriented concepts.The Third Manifesto which is written by Darwen and Date 1995 rejected both the object-oriented ideas and SQL which according to them defeat the relational models ideas, and to return to the genuine relational model and Codds 12 rule. The document produced for this manifesto is very controversial, from the circulating(prenominal) way software engineering and query/programming languages are done now. The arguments presented in this manifesto are more ideological rather than technical and this make the manifesto very difficult to be accepted by many databases professional. The newest version of the manifesto (2006) still retains these ideological assertions.Object-Oriented Database Management System Development reviewOODBMS stores Objects rather than data such as Integers, strings and real numbers, Objects consists of Attributes and MethodsAttributes They are data that defines the characteristics of an object. This data may be integers, strings and real number, or the data may be a reference to a complex object.Methods This defines the behaviour of an object and methods are procedures or functions.The introduction of OODBMS was to reduce impedance mismatch between programming languages and database manageme nt system, to offer performance advantages and to provide clear support for complex user defined type including the ability to call, store and query complex object directlyThe developments of OODBMS support the modelling and creation of data as objects, extends programming languages with capabilities like data recovery, concurrency control, long and other relational capabilities. OODBMS are used when there is a need for good performance processing on complex applications because it takes a revolutionary approach to database management. OODBMS do not use table to store data, data are stored in objects and it handles con latest access and provides a persistent store for objects in a multi-user lymph gland/server environment. OODBMS uses class definitions and traditional Object Oriented languages such as, C++ and Smalltalk for defining and accessing data instead of using separate language like SQL in defining, manipulating and retrieving data. OODBMS can be viewed as an extension of the OO language, providing direct desegregation to database capabilities.Object-Oriented database development initially focuses only on application that manages complex information like the Computer back up Software Engineering, Aided Manufacturing (CAM) and Computer Aided design (CAD) applications.Other applications where object-oriented database technologies are now being used includeTelecommunications applicationsHospital applicationsFinance institutions Multimedia applicationsDocument/quality management OODBMS development enforces object oriented programming concepts such as data encapsulation, polymorphism, object Identity, inheritance as well as database performance management concepts e.g the acrid PROPERTIES (Atomicity, Consistency, Isolation and Durability) which mend the integrity of the system.. OODBMS also support secondary storage management systems with ad hoc query languages , these permits the management of very large data.The inclusion of data definition within operations definitions in Object Oriented Database Management System has the following advantagesThe defined operations are not dependent on the database application running at the moment and they apply ubiquitously. Inheritance allows the development of solutions for complex problems incrementally, and this is achieved by defining new objects in terms of the previously defined objects. Extension of Datatypes to support complex data such as multi-media, this is done by defining new object classes which have operations to support the new kinds of information.Object identity (OID) enables objects to be independent of each other in the database. Data encapsulation, this allows the internal state of the object to be hidden. Objects that are encapsulated are the ones that can only be assessed by their methods instead of their internal states. There are three types of encapsulated objectsFull encapsulation, here all the operations on objects are performed by means of message sending and by the execution of method. Write encapsulation, here the internal state of the object is allowed for reading operations only.Partial encapsulations, this allows direct access to reading and writing to some part of the internal stateAnother distinguishing characteristic of objects is that they have an identity that is independent of the state of the object. For example, if one has a car object and we remodel the car and change its appearance, the brake and the tires so that it looks entirely different, it would still be recognized as the same object we had originally before the changes were applied. Object-identity allows objects to be related as well as shared within a distributed computing network.All of these advantages come together to provide significant help to database application developers making development easier. The advantages also allow object-oriented databases development to solve information management problems that are characterized by the need to manage A large n umber of different data types, A large number of relationships between the objects, and Objects with complex behaviours. An application development where this kind of complexity exists includes engineering, manufacturing, simulations, office automation and large information systems.Currently there is no widely agreed standard for what constitutes an OODBMS and no standard query language for OODBMS that is equivalent to what SQL is to the RDBMS. The Object Data Management concourse (ODMG) a consortium of Object-Oriented Database Management System (ODBMS) vendors and interested parties working on standards to allow the portability of customer software across ODBMS products and to create a standardized Object Query Language (OQL) and object definition language (ODL).The work of ODMG on object data management standards completed in 2001 and the group was disbanded. The final throw in of the ODMG standard is Object Database Standard (ODMG-3.0).Because the ODMG group was dissolved in 20 01and this made the standardization of Object database languished. Another group was formed in 2005 called the OMG,s Object Database Technology Working group (ODBTWG) which is now working on a new standard to reflect recent changes in OODBMS technology.The main features of an OODBMS development is the way in which object is access in a transparent way such that interaction with persistent objects is the same as interacting with in memory objects. RDBMSs require the use of interaction through a query sub-language like SQL and the use of ODBC, ADO or JDBC. All this is unnecessary with OODBMS. In OODBMS when a request is made for an object in the database, the object is transferred into the applications cache where it is either used as a temporary value that is detached from the main version in the database so any updates to the cached object will not affect the object in the database. Object can also be used as the exact copy of the version in the database, so here any updates to the object are shown in the database and any changes to object in the database means the object has to be retrieved again from the OODBMS.There are a number of implementation of OODBMS with both research and commercial application. Each implementation is different based on the Object oriented languages, which form their origin. Some of these developments are discussed belowGemstone This was mainly based on smalltalk and its data definition and manipulation language is called opal. Gemstone do not provide all of most of the object-oriented features, it does not provide multiple inheritance.Iris This is a research prototype, with the purpose if meeting the needs of applications like CASE tools, CAD etc. (Fisman et al (1987). It is designed to be accessible from any number of programming languagesVBase This is commercially available and is built with a schema definition language concept when objects are defined as data types. The main purposed of Vbase is to combine the procedural languag e with persistent object support, it also has the strong typing inherent in object systems for both language and database.O2 This is based on the framework of a set and tuple data model. It is designed with the purposed of integrating database technology with the object- oriented approach, for an all in one system. (Lecluse , et al 1988) Most of the OODBMS development discussed, tried to meet object orientation approach in someway, they do this by implementing various OODBMS features. There are major differences in the physical implementation of each model as well as the number of features implemented.Two Examples of companies using OODBMS are British Telecominication uses Versant Mclaren develop the Formula one racing car uses Jasmine OODBMSComparison criteria between RDBMS and OODBMS including the pros and cons.RDBMS and OODBMS differ in many ways example is in application domain, performance, usage, current market demand and support from vendors. RDBMS and OODBMS comparisons are done to get a better understanding for how the two databases differ and why OODBMS is better for large complex applications.A significant difference between object-oriented databases and relational databases is that object-oriented databases represent relationships explicitly, supporting both navigational and associative access to information data. As the complexity of the interrelation between database information increases, so is the advantage of representing relationships explicitly increase too. Explicit relationships usage also improves data access performance over relational value-based applications. maintenance for Object Oriented Programming Language (OOPL)Object Oriented Programming is not ideal for RDBMS, programmers spend most of the of coding time mapping the program object to the databaseIn OODBMS, programming is direct and extensive, OOPL are designed to allow an application developer to create a complex sequence of instructions with less hindranceStandardsThe define d standard for RDBMS is SQL, with main elements being DDL, DML DCL. The current version of the standard is SQL 3, SQL 3 defines the new features used in ORDBMS.ODMG is the group that maintains the standards for OODBMS the main components of standard being ODL and OQL. Most recent version of this standard is ODMG-3.0 and there are no new standard yet to reflect the advances in OODBMS technology.Product MaturityRDBMS is a second generation and in a much matured stage. RDBMSs have good implementation with many support services such as the tool support for reporting, data transformations, OLAP tools etc. RDBMS is available from many vendors this made it an obvious choice for most of the users.OODBMS is the 3rd generation DBMS making it relatively new, it emerged after the RDBMS, new ODMG standard still not in the final stage. Some implementations are available but still do not fully support all the features.Simplicity of use The table structure in RDBMS is very easy to understand by us er and also RDBMS has many end-user tools.OODBMS is mainly for developers, not many end user tools are available for object database products but this is hopefully expected to improve over time.Versioning of DataVersioning of data is not support by RDBMS but the user using multiple records with some of the attributes describing the versioning information can implement this feature. Versioning are defined by the userVersioning is supported of course by OODBMS this is to maintain multiple versions of the data objectsComplex data relationships RDBMS provides basic relational tables, user-defined sets of records with system-defined domains, in addition to more high-level types defined in application.OODBMS has the same type system for system-defined and user-defined types. It is open-ended.PerformanceOODBMS performed better than RDBMS based on the Object Operations version OO1 benchmark that was done on the OODBMS software (GemStone, Objectivit0079/DB, Ontos, Objectstore) and RDBMSs (I ngres and Sybase) in 1989 and 1990. Object in OODBMS is a better model of the real world entity than the relational rows in regards to complex applications. OODBMS outperform RDBMS when it comes to handling complex and interrelated data. Also the lack of impedance mismatch in OODBMS means they provide significantly better performance than RDBMS. Impedance mismatch require the mapping of one data structure i.e. tables to another data structure i.e. objects and this slows down performance on in RDBMs. Also the client catching features in OODBMS improve performance and also no joins are required in OODBMSApplication DomainRDBMS is used for large administrative systems, with many instances of simple data types it can only handle short transactions and few data at a time.OODBMS is for design applications, with many and complex object oriented data types, handles long transactions and large client data.Semantic Gap (DDL/DML Vs. PL)RDBMS offers relational tables in some DDL and a standardi zed DML with client/server support and with embedded SQL in many Programming languages(PL). SQL is not computationally complete. Applications may have further, often high-level types and special storage structures expressed in some PL.In OODBMS, same OBJECT-ORIENTED PROGRAMMING LANGUAGES like C++ and small talk is used for both client and server. It does accommodate only object-oriented languages and does not accommodate cobol. The database PL is computationally complete.Query Optimization This is very strong in RDBMS because of the restricted set of data type.OODBMS has poor query optimization because of the complex data structurePrimary Keys In RDBMS rows are uniquely identifying based on the value and also no two records can have the same primary key values this is to avoid error conditions. In an OODBMS, Object Identifiers (OID) which are system generated are used to uniquely identify an object and this is done behind the scenes and this is completely invisible to the user. With this feature in OODBMS there is no limitation on the value that can be stored in an object, thus increasing the efficiency of the database.Vendors Support RDBMS is highly successful because of the large market size but most of the vendors of RDBMS are adding the capabilities of Object oriented to their applications so they are moving towards ORDBMS.OODBMS are targeting niche market because they lack of support from Vendors. This is due to the fact that the market for RDBMS is very large and it is difficult for vendors to move away from legacy systems that are mostly based on RDBMS.OODBMS Functionality and performance reviewComplex process integration among companies is the driving force for adopting OODBMS. The capabilities of Objected-oriented programming language are integrated to the technology of DBMS in OODBMS. Designs of Object database are quite different because object database design is the essential part of the overall application design process. In OODBMS the Object clas ses used is the same as the classes used by the programming language.Data are stored in tables with columns and rows in relational databases i.e. data are represented in two-dimensional view. This is effective for applications that are simple, straightforward system, possessing low volume. RDBMS is good for application with simple relationships between data. Relational database technology failed to handle the needs of complex information systems because it requires the developer to force an information model into tables where relationships between entities are defined by values and, Relational database requires translation of sub-language like SQL and call interface like JDBC/ODBC. All these slows down the RDBMS data performanceSupport of abstract object interfaces is actively provided by OODBMS. It manages types, classes and methods, including the execution of methods. Data can be represented in more than two-dimensional view and relationships between data are represented explicitl y which improve data access performanceThe basic functionality of relational database management systems is combined with new functionality of Object oriented in OODBMS. The basic functionalities arePersistenceTransaction Management and Concurrency controlSecurity RecoveryData Access performanceQuery. Persistence This is the ability of an object to be stored on a permanent modal(a) and can survive program termination or shutdown. i.e. it can survive the duration of the OS process in which it resides. Persistence data to survive transaction updates they have to be stored outside transaction context. The addition of persistent to objects is essential to making OODBMS applications useful in practice this because most applications need to handle persistent data. Persistence is dealt with in OODBMS by the addition of persistence to object programming language like C++, Smalltalk and Java. OODBMS support persistent objects from data distribution, programming languages, transaction model, versions, schema evolution and generation of new types. Another way OODBMS offer persistence is through Inheriting from a common class.Transaction Management and Concurrency control The use some form of versioning systems is the means of managing updates to multiple data at the same time in OODBMS, without any interference from one another. OODBMS products allow the objects to die hard in the client cache after committing a transaction this is done so that the application is able to reference it again soon. This feature increase performance with the way data are stored and retrieved from the database. Concurrency control enables users to see the same view of object data in OODBMS. This allows a lot of reads and writes operations to go on in parallel while ensuring that the data is in consistent and good state.Security Secure OODBMSs have certain characteristics that make them unique. The concepts of encapsulation, inheritance, information hiding, methods, and the ability to model real-world entities in object oriented environment provide security model in OODBMS. OODBMS may encapsulate a series of basic access commands into a method and make it public for users, while keeping basic commands themselves away from users. Little work has been done in OODBMS application to add security weapon against malicious misuse of data.Recovery Recovery features in OODBMS allow a consistent state of the database to be reinstated after a system crash or failure. This is done by either by rolling back the uncommitted transaction or rolling forward of transactions that has been committed but not completely flushed to disk.Data Access performance

Have you ever heard someone say, "I hate all medication."? Lately though music has been criticized for corrupting teens minds. Hip Hop is being blamed for all the crimes and murders in cities all over America and heavy metal is being blamed for cock-a-hoop teens only dark images and thoughts in their minds.      First we must ask what Hip Hop is to us or to others, who simply dont know or may never feel our movement in society. This form of poetry and story telling has took growth from within a deprived New York realm during 1970s is spread worldwide, even non-english speaking countries strive on our message to help their culture the light. Hip Hop has taken my generation in capable arms and speaks the truth to those, who listen. We are more motive and attentive , better focus I believe then any generation before us. In the United States we take pride in ourselves as being the freest nation in the world. Unfortunately, there are times in our history i n which sure groups have been unrightfully deprived of their freedom. This can be said for Americans who endured years of ignorant and another century of unawareness. Is which I think started the late 1970s signaled a crude era of rhythmic and linguistic wealth rap music. Hip hop and in particular rap music gives people on the margins of society a powerful voice to express political discontent. While political discontent is expressed through all the elements of hip hop, rap music has bec...

Troubled Bruno in The Hostage :: essays research papers

The HostageA hostage inside himself, and troubled soul that has had genuinely many bad influences in his life. Bruno, a boy, makes many mistakes and has had very many tragic instances like his father dieing, and nothing will, and can go right for him. As the reader will find out is he is very quiet and has a macroscopical stature that was feared by many, and has a lot of things that trouble him. Bruno goes though a tough time and bad situations that help influence his actions, feelings, and words, though his life, and secures him hostage within himself.Bruno was very built and had a very large physique, which raft found threatening and scary. He looked much older than scour angiotensin converting enzyme as if he was in junior high. His hair was sleeked back and was very distressing and oily with a large neck and shoulders. Even though he had this big overpowering body he let it be known to either one with the cloths he wore. He showed he was tuff, and muscular though those c loths. Bruno also had a scare one his forehead that rumors say he got when a fold of boiling water in a pan hit him. They think he may have pulled it and it fell or his mom dropped it. Through this large stature one might see how he was probably made fun of and harassed. He spoke English with a strong accent, musical, yet hatful mocked him and embarrassed him silently(1201). Written by Joyce Carol Oates the write of the Hostage. This lowered his self a steam that he held in anger and used it to hold himself hostage with in.Other people in Brunos class were scared of him and though being scared they revereed him. Because he had this kind of scared respect for him he was voted class president and was left alone. People stopped seeing him at school for a while and soon found out that his dadaism died. He was killed in the mafia, which affected him strongly. When he came back no one said anything and at this time he really need some one to talk too. But no one did because they were scare of him. The only person that came was the narrator was the only person who even came up to him and he did not even let her say it. But she could tell that he really enjoy her even coming up to him to attempt to talk to him.

Conduct Disorder Essay -- Psychology Children Psychological Essays

Conduct Disorder As immediately as infancy, tikeren express individual characteristics that can be considered combative. The child can be aggressive in the way it cries, the way it plays and the way it attains attention. P bents of children that have a hard time sleeping through the night, trouble accepting affection and/or difficulties with hyperactivity are often so stressed and twainered by these behaviors that they resort to negative reinforcement techniques in their parenting. Examples of this can be perceiven in spanking, harsh reprimanding or eve ignoring the childs behaviors. By using negative reinforcement, the parents are unknowingly strengthening the prevalence of these behaviors, and therefore, the risk of these types of activities to continue through adolescence is also heightened (Patterson, 1982). Children who tend to non comply with authority in infancy have a greater chance of having an aggressive temperament in adolescence (Kolvin, Nicol, Garside, Day & Tweedl e, 1982 Olweus, 1980 Webster-Stratton & Eyberg, 1982). Therefore, as difficult children fuck off adolescents, they present an even greater challenge for their parents, school officials, law enforcement and the community. Often ignored is the biggest challenge, which is the child dealing with this instability of his or her mental well-being. We will see in the research provided that conduct disorder is multifaceted, consisting of some components which are hard to conceptualize and of others that are common knowledge. However, each aspect is crucial in misgiving the scope of this mental disorder, starting with its history of violence and ending with its lacking intervention.Conduct Disorder is the most common psychiatric disorder in childhood, impact approximately 7% of boys and 3 % of girls in the general population (Meltzer, Gatward, Goodman, Ford, 2000). Unlike most mental disorders, which afflict solely the diagnosed party, conduct disorder has serious implications for both the subject and the rest of society. Violence, over aggressiveness, and inappropriate behavior, such as stealing and drug and/or alcohol abuse, are all frequently expressed characteristics of the disorder, however, it is not, by far, limited to these three alone (Campbell, 1990).

The Fourth Strike :: essays research papers

The Fourth StrikeIn Joe Rodriguezs article Kids and Alcohol Dont Mix, Rodriguez states that the new proposed legislation introduced by Senator Dede Alpert exit make it extremely difficult to close down retailers who consistently sell booze to minors. I completely agree with Rodriguezs point of view because it willing make it easier for retailers to continue illegally selling their products to minors by allowing a one-fourth strike.In California, the law allows the Department of Alcoholic Beverage Control (ABC) to make for any retailers license after three strikes of selling alcoholic drink to minors in three years. The new proposed law would allow one of the strikes to be interpreted away if the retailers train their employees to check IDs and install electronic scanners to read IDs and spot fakes. I feel that this new proposed law is too forgiving since it gives this unofficial fourth strike for retailers to continue selling alcohol to minors. According to testimony given to t he California Council, Alpert claimed this measuring was a pr so fartion bill, however, I feel this is not even close to a prevention bill at all, but an undermining of local prevention efforts to alcohol enforcement groups.One of the enforcement groups that will be undermined by the new bill would be the Department of Alcohol Beverage Control. Prior to the proposed law, the ABCs system consisted of under cover minors who go into stores and try to buy booze. formerly they catch a retailer who sells them alcohol, they immediately report them to the ABC. I agree with this approach because it puts the majority of the blame on the clerks of the retailers who sell to minors. The retailers serve as the ones almost responsible because they are selling to minors and in a way they have the role of the adult to minors when it comes to selling alcohol to adolescents. During my junior year, I attended a birthday get together with a couple of my buddies. What started was a very jubilant party , then turned into a night shape to the liquor store. I remember being embarrassed after my friends pulled off the alcohol run after the clerk let my friends go off with the alcohol without any hesitation. I recall thinking how irresponsible the clerk was to let a bunch of seventeen year old boys off with alcohol and the dangers that it could entail.In 2000, California legislation passed the California Alcohol Control Act.
